3 Claims. (Cl. 171-329) My present invention has as its main object theprovision of methods and means for generating very high potentials orvoltages at high energy levels.

In one way of carrying out my invention for the generation of highdirect current voltages, I charge metallic units, preferably particlesof metal, by actual conductive contact with a direct current source.Then, by moving the particles away from the source, the voltages of thecharges thereon are increased, in a manner which will be explained morefully hereinafter, and the charges are ultimately deposited upon a lowvoltage gradient-section of a charge-storing device or container.

This application is one of several divisions of my original patentapplication, Serial No. 684,328, filed August 9, 1933, which has nowmatured into Patent #2,210,492, dated August 6, 1940, which contains,but does not claim, the identical disclosure of .the instantapplication. The parent patent application contains claims directed-tothe belt system and also the combined belt and disc system. A firstdivisional application, Serial No. 4,475, filed February 1, 1935, whichhas matured into Patent 2,070,972, dated February 16, 1937, containsclaims directed to the rotor system wherein an inductive principle iscombined with centrifugal force and utilized to increase the outputvoltage. A second divisional application, Serial No. 8,236, filedFebruary 26, 1935, which has now matured into Patent 2,119,588, datedJune7,1938, contains claims directed to the high voltage generatingsystem wherein charging units are arranged in parallel with meansprovided to discharge them in series. A third divisional application,Serial No. 81,360, filed May 23, 1936, which has matured into Patent2,171,242, dated August 29, 1939, contains claim directed to a highvoltage generator com-' applied to gases.

In another arrangement for producing high voltages according to mypresent invention, an induction electrode, either grounded or prefer- Rably maintained at a high voltage, is insulatingly separated from achargeable medium which may be a solid, a liquid, or a gas, and, by theuse of a point discharge electrode system connected to a direct currentsource or preferably to ground, ionization or corona is caused to .takeplace through and/or about the chargeable medium.

The charged medium is then moved or carried A further and more specificobject of my" present invention is'to provide systems which utilize myimproved contact and induction principles.

This description will be given in greater detail with the aid of theaccompanying drawing which, however, is not to be considered in any wayllmitative of my present invention but is to be considered onlyillustrative. Referring now in detail .to the drawing:

Fig. 1 is a sectional view wherein the high potential voltages areapplied to gases;

Fig. 2 is another method of charging a metallic container to a highvoltage by the use of gases.

As an example of the manner in which my improved induction system forgenerating high voltages may be applied to gases, particular referenceis made to Fig. 1. By virtue of a motor 508 driving a pump 510, oil issprayed through nozzle 5i2 vertically through glass pipe or insulatingcylindrical chamber 5l4. Air sucked in or pumped in through ball valveSit and orifices 5l8 forms bubbles with the oil. Instead of air, othergases such as helium, nitrogen or mixtures thereof may be used. Byapplying a high voltage to the electrode 520 through conductor 522 froma suitable source (not shown) corona discharge will take place at themetallic points 524 mounted on a metallic grounded electrode 526. As aconsequence, the air in the oil bubbles becomes ionized, passes upwardlyinto the metallic elbow 528 and through metallic wire screen 530.Consequently, the charges are fed on to the metallic false bottom 532 tothe interior zero gradient surface of the sphere 534, whose outersurface rapidly becomes charged to an exceedingly high potential. Excessoil may be carried ofl through glass pipe 536 to be repumped throughpump M0.

The system shown in Fig. 1 may be applied to advantage in internalcombustion engines. In that case, the air supply would be completelyshut off but the gasoline sprayed past the corona points 524 wouldcharge up the particles of gasoline. The gasoline could then be fed intothe combustion portion of the engine with air and the resultantexplosions should give relatively greater power and more completecombustion than that now available in the ordinary type of gasolineengine, due to the beneficial action of the ionization.

Another way of charging a metallic container to a high voltage by theuse of gas is illustrated in Fig. 2. Air is blown through a pipe 550past a plurality of discharge points 552 whose terminals, asillustrated, are connected to ground and to the high voltage side, offor example, an induction coil. I'he ionized air is then blown through ametallic screen 554 which may be maintained at a positive or negativepotential, depending upon the character of ions desired. The screen 554will remov ions of opposite polarity as a result of which ions blownthrough glass tube 556 impinge upon the shell 558 and lose their chargeto charge up condenser or storage device 558 to a plurality oppositethat of screen 554.

The ions emanating from glass tube 556 need not, however, be used forcharging purposes but may be inhaled for medical treatment, that is tosay, used therapeutically. If desired, a series of screens 554 may bearranged at the same polarity but of different values or at the samevalues of potential so as to insure obtaining ions of merely onepolarity. For medical purposes, ions of either polarity may be used tothe exclusion of others depe ding upon which type is found more helpful.

Various changes will readily suggest themselves in carrying out theprinciples of my present in vention. Accordingly, my present inventionis not to be considered limited by the various illustrations given buton the other hand is to be given the full scope indicated in theappended claims.
